Exposing knowledge gives people love, light and wisdom. It should be said that knowledge is happiness, because with knowledge, we feel the pulse of human activities in history, otherwise we will not understand the movement of human life!

This knowledge, like a rainbow, lights up the lamp in Helen's heart, illuminates her inner world and builds a bridge between Helen and the world!

It is knowledge that gives her the courage to live, and it is knowledge that gives her the strength to accept the challenges of life, so that she can face difficulties with amazing perseverance and finally find the light of life in the dark. It was knowledge that gave her new faith.

In this world, why do only deaf people cherish the restored hearing? Only the blind will cherish the happiness of seeing the light of day? Let's cherish every day of our lives, enrich our lives and enjoy them.

How powerful knowledge is, it can turn a disabled person into a person who is beneficial to human beings and society. If each of us can, like Helen Keller, regard the thirst for knowledge as the pursuit of life in our lifetime, and lead a friendly, energetic and eager life with this pursuit, how much joy and happiness will our life add!
